Lucas Aparecido Oliveira Dos Santos: The Online Chess Grinder
Known to the chess internet as lukazz029, Lucas Aparecido Oliveira Dos Santos is a National Master whose online play reads like a love letter to fighting chess. He prefers the slower pulse of rapid chess, but his real addiction has always been the chaos of blitz and bullet. With more than23,000 rated games played, he has turned the internet inta a giant chess laboratory.
From 1300 to National Master
Lucas first appeared on the rating radar in early 2016 with a modest1351 blitz rating, but within weeks he was already knocking on the door of2100. That kind of trajectory did not stop. Year after year, he piled up games, absorbed every loss, and transformed online chess inta a training ground for his eventual National Master title.
By September2026, his blitz rating had surged toa massive 2627 (2026-09-05), while his rapid game reached 2310 (2026-09-07). The overall map of his climb looks like a mountain range with a few valleys, which is exactly what you would expect from a player who has played more than23,000 rated encounters.
A Fighting Spirit with a Comeback Button
Lucas is not the type to resign early. His early resignation rate is just3.62%, and his endgame frequency of67.74% shows a player who is willing to drag opponents into the longest, most exhausting phase of the game. His comeback rate sits at84.34%, meaning when he loses material he does not simply collapse, he finds resources at the board.
- Longest winning streak:18
- Longest losing streak:17
- White win rate:51.43%
- Black win rate:47.04%
He has a pronounced appetite for beating lower rated opposition, where his win rate jumps to64.97%. When he is outrated he still fights toa30.78% win rate. In other words, he is dangerous when expected to win and annoying when expected to lose. He even wins48.38% of games after losing a piece, which is absurdly high and explains why he never gives up.
The Grinder's Repertoire
As Black, Lucas has a special relationship with the Sicilian Defense. He has played it thousands of times, especially the Najdorf Variation, and he scores particularly well in rapid when he can steer the game into those razor sharp lanes. Against1.e4 he also rotates in the French Defense and Caro-Kann Defense, accepting closed, complex positions rather than trying to refute everything in one move.
With White, he has evolved over the years from a devoted1.e4 attacker inta a practical d4 and c4 player. He loves shuffling his opponents out of their preparation and backing them into endgames where his patience pays off.
Familiar Faces in the Lobby
No online career is complete without rivals, and Lucas has collected several. His most frequent dance partner is Julio Cesar Fernandes de Sousa, with whom he has played a staggering268 games. That rivalry has not been kind to him, though: he has only88 wins against158 losses and22 draws. On the other hand, Ricardo Maruchi Desideri has usually walked away with the short end, losing141 times in211 meetings while Lucas took141 wins. And when he meets rodrigoarodriguez, it is close toa highlight reel: Lucas has64 wins and only4 losses in70 games.
The Clock and the Grind
For all his love of rapid chess, Lucas has logged blockbuster numbers in blitz and bullet. His bullet rating has also climbed to 2428 (2026-08-04), and his rating graph from2026 is almost vertical. His best hours appear to be the early morning, particularly7:00, when his win rate spikes to63.33%. Perhaps coffee is involved, or perhaps his opponents are still asleep.
His game length statistics are telling: his wins last on average about70 moves, while his losses end about57 moves. He grinds until the bitter end rather than flagging under pressure. His inner demon is the tilt factor, which sits at17. That tilt doubles as his longest losing streak, but he can spiral and then climb back out, which is exactly what a true online chess warrior does.
