Here the black h-pawn comes in handy.It protects from escaping the black king.

There are a lot of perpetual checks. It's a draw.

Yes.

**Alena**

It's because of Rb1+.

However, before looking at the tablebase, do consider black's options after 6.g8(Q) to understand why black can win. It is important in finding the solution.

Alena, the position is los after 1.Rxh4?? You can confirm this by looking at the Nalimov Tablebase after Black's fifth move.

We reached the position: 6Q1/1k6/8/8/1Kp5/8/8/3q3r w - - 0 1. It's a critical position for white. Now white must be very cautious. The goal for white is to destroy the black c-pawn and give perpetual checks.The white queen must give precise checks so that the black queen couldn't protect the black king from checks.
