Tomas Sosa GM

Hi Tomas, here is some tailored feedback based on your latest blitz games

What you are already doing well

• Dynamic opening choices. You comfortably switch between the French, Sicilian and various Indian set-ups as Black, and between 1.e4 and 1.d4 systems as White. This keeps opponents guessing and shows a broad knowledge base.
• Initiative-oriented play. In your recent win versus i_fink_u_freeky you seized space with …c5 and …b5, then converted an extra pawn in a rook ending. Your willingness to push the initiative is a clear strength.
• Rook-ending technique. The conversion against Juan Carlos Obregon Rivero (January 10th) was model: you activated the rook, fixed targets, and restricted counter-play before queening a pawn.
• Tactical vision under time pressure. Many wins arrive with both clocks under ten seconds, yet you still spot tactics (e.g., 33…Nxe5+!! on 15 Apr). Your puzzle-like sharpness is above average for your rating.

Key themes to improve

1. King safety after flank pawn pushes.
   • Loss vs 0blivi0usspy (Torre Attack, 6 Jun): early …g5/…h6 weakened the dark squares and cost the game.
   • Loss vs GilbertElroy (E10, 15 Apr): drifting king side-stepped into mate after …b6 without completing development.
   Action: When you play …g5, …h5 or h4/h5 in the French & Sicilian frameworks, add a “checkpoint” to ask: “Does this create more weaknesses than it solves?” Run those positions through an engine to see typical refutations.
2. Time-management consistency.
   You won four recent games on the clock but also lost to FarewellToKings2112 by flagging from a drawn rook ending.
   Action: Practise 1-minute “increment drills”: start with 10 s on each side, 2 s increment; play bot positions that are +2 but technical. The goal is to learn when to cash in material rather than search for the prettiest continuation.
3. Defence against the Torre & London structures.
   Two June losses began 1.d4 Nf6 2.Nf3/3.Bg5. You allowed Bf4/Bg5 lines to dictate the middlegame.
   Action: Build a mini-repertoire: either (a) early …h6 and …d5 with c5 break, or (b) the solid …Be7–…d6 setups. Create a 20-move move-order file and drill it vs engine.
4. Transitional tactics from middlegame to endgame.
   In the Torre loss you missed 35…Rxb3! but then overlooked that 38…Rc3? entered a mating net.
   Action: Add 15 minutes of daily tactics filtered for “quiet” engine evals (+/–1 to +/–2). This trains you to notice less obvious resource checks, zwischenzugs (zwischenzug), and perpetual motifs.
