Thanks for the information.

The position is from a game in the final of the championship of Israel in
correspondence games.

GM Abir Har Aven(ICCF rating 2585) is against me.

Abir (white) started 1.g3 d5 2.f4 h5 3.Nf3

I already played h4 and it is Abir to move.
I find that tiger plays h4 with the plan h4  Nxh4 Rxh4 but after giving tiger
the position after h4 Nxh4 it wants to play e5 with a different score(more than
+1 after a few minutes).

I expect Abir to play Nxh4 and I will have to decide if to play e5 or Rxh4.
