Improve Your Chess: Tricky Opening, Simple Tactic
Opening: A04: Reti Opening: Lisitsin Gambit
White plays an unusual gambit but misses a fourth move which would keep his advantage normal. Instead a series of small errors adds up to a queenless middlegame with White down a pawn. White tries to create counterplay but Black's solid play is more accurate. Finally White allows a removal-of-the-guard tactic and resigns, although he could have forced Black to find one more accurate move before the demise.
