After 1.Qe1 Qg2! black threats mate again. 2.Ra8 is a thematic try, te plan is Rh8+ and after Qe8+ which leads to stalemate. Black defends the stalemate by a fine move Qc6! and after this avoids the perpetual check too. Therefore the correct play is: 2.Rf3! and 3.Qe4+. This is a solver friendly study with rich content.} 1/2-1/2

In the main line after the exchange of queens the King is on g4 ( white can play Rg3+), but in thematic try on h4. In the main line white has a winning material advantage, but he has to defend himself against black's traps. It is exciting to see the pieces chasing each other.} 1-0
